A spray device for dispensing a cooling fluid comprises a reservoir in which the cooling fluid is stored in liquid form at an overpressure, a fluid outlet valve, and a spray head (3b) which has a capillary tube (30b). The capillary tube (30b) is arranged in a valve tappet (31b) in such a way that the inlet end of the capillary tube (30b) is connected to the fluid outlet valve of the reservoir and causes the cooling fluid to pass into the capillary tube (30b) when the fluid outlet valve is actuated. In the reservoir, there is a further capillary tube whose inlet end extends into the cooling fluid stored in the reservoir, and whose outlet end is connected to the fluid outlet valve. |
